16S rRNA-based analysis of the gut microbiome in 1126 twin pairs from the United Kingdom revealed that certain species containing Bifidobacterium was heritable and fabricable
. Like the gut microbiome, there may be genetic factors in the origins of lower airway microbiome .
(11) In addition, due to their higher costs and process complexity along with issues of environmental pollution caused by those coating materials, research frontiers shifted toward developing low cost, easily fabricable
, and environmentally friendly materials.
Therefore, [[LAMBDA].sub.4] was increased to make the rectangular teeth's depths fabricable
(the minimum fabricable
track/gap size is 100 [micro]m for our technology).
